I went to historicon a few weeks ago and watched a 1/72 WW2 airbattle game for a few minutes.  It was interesting in that some waves of B17. and Lancaster were fling across a HUGE table of carpet remnants.  Being (stupid spell check) Machine gunned by German BF and FWs while the allied fighter escort was failing "navigation rolls"  flying in random circles via scatter dice results.  The bomber players were NOT amused.
